Abstract

In this work, mathematical models of surface plasmon resonance (SPR) biosensors are proposed. The proposed sensor with transition metal dichalcogenides (such as PtSe₂) constructed of two-dimensional materials (BP and WS2). Traditional SPR biosensors are also discussed. In the field of SPR sensors, researchers have been very interested in 2-D materials. Figure of merit (F.O.M) and sensitivity are two important parts of SPR sensors, and it has been talked about with analyte ranges from 1.330 to 1.36. The proposed sensor was found to be most sensitive when it had just one layer of Platinum diselenide (PtSe₂) and two layers of black phosphorous (BP). Here, a heterostructure made of BK7 Prism/Ag/PtSe₂/WS₂/BP is proposed as a much sensitive SPR biosensor with a Kretschmann configuration at a wavelength of 633 nm. The attenuated total reflection (ATR) method is used to measure the sensors' sensitivity, figure of merit (F.O.M.), Minimum reflections (R_min) and detection accuracy (D.A). The proposed sensor has many uses in biomedical, chemical, and bio-sensing fields.
